The Humble bundle has LOG with Linux version. Runs great. For some reason for me, the menu item dosen't work (could be because I'm using MATE), but if you go to where it was installed /usr/local/games and run that, it works perfectly.

Was able to get around the shortcut problem by making a shell script with this in it:

cd /usr/local/games/Grimrock./Grimrock.bin.x86_64

and then using that for the menu item. Might not happen to you, but thought it may help just in case.

I have the game from Humble Bundle and I also unlocked it on steam, but I'm on Ubuntu, so I play it by launching it from the shortcut I've added inside steam. It's not completely the same thing, because it doesn't take into consideration any steam achievements, but besides that, it's all good. I guess it's just a matter of time, anyway, the sooner the better. Almost Human is probably losing some nice amount of sells already.
